AUTOLIOBILE RADIATOR ATTACHMENT.

Application filed-September 18, 1920. Serial No. 411,255.

To all whom it may concern:

Be it known that I, Jomrv F. WHITE, a citizen of the United States, residin at Chicago, in the county of Cook and of Illinois, have invented certain new and useful Improvements in an Automobile Radiator Attachment, of which the following is a specification.

This invention relates to a new attachment for automobile radiators, the same being in the nature of a cap or closure device for the radiator nipple, arranged to carry a temperature indicating instrument or other display device, and constructed in such fashion that it can be secured in place on a radiator nipple of conventional or standard type in a manner to frustrate its "unauthorized removal,

The specific mechanism herein disclosed for effecting this obect includes in the present instance, a com ination lock of any desired or well known construction, the bolt of which, when projected, connects the tube closing cap to a threaded bushingby which the cap is mounted on the automobile radiator nipple. When the bolt is retracted,

on the other hand, the device is disconnected from said bushing so that the same cannot be detached from the tube b rotation of the cap. A construction embo ying this inventive idea is illustrated in the accompanying drawing, in which-- Fig. 1 is a side elevation and central vertical section of a cap and motor meter mounted on a radiator nipple;

Fig. 2 is a plan view of the same with the motor meter nipple in section on line 2-2 of Fig. 1; and

Fig. 3 is a view from below with the radiator nipple in section.

Fig. 4 isa transverse section of a form of combination lock, same being taken on line 4-4 of Fig. 5.

Fig. 5 is a cross section of the same. i In these views, the numeral 1 designates the nipple of an automobile radiator, 2 the cap and 3 the arms by which the same is retated. The numeral 4 designates a device sometimes known as a motor meter, the stem 5 of which passes through and is secured b nut 6 to the casing 7 of a combination loc the internal construction of which may be of a common form and of itself constitutes no part of my invention. "or form tate.

ment, the

.over the bolt, frees the externally threaded bushing of lock which may be utilized is illustrated in Figs. 4 and 5. Such lock includes a substantially c lindrical casing 7 provided with an axia aperture for the passage of the operating mem er, which in this instance is the stem of the motor meter. Within the casin 7 1s slidably mounted the lock bolt 11, a apted to be projected through a side 0 enmg 1n the casing by the spring 20. cans for retainin the bolt retracted withm the casing inclu e a freely rotatable ring 21 adapted to engage in a groove 22 in the bolt, and an operating disc 24 having a depending flange 25 adapted to engage an abutment 26 on the bolt. The disc has a central aperture for the passage of the operatlng member, to which it is operabl connected in suitable fashion, as'by the ug 27 v which fits in a keysway.28 in the stem 5. The ring and disc have engageable members 29, whereby the ring may be rotated in the casing by rotation of the disc. So long as these enga mg members arenct in en ageof the ring. The ring is formed with a we may be rotated indepen ently clearance recess 30 which, when positioned 1 0 same from any restramt of the rin and the flange 25 of the disc also has a c same pur ose. Adjacent the recess 31, the flange 25 1s deflected inwardly to providea restoring cam 25, which is adapted for cooperatlon with the abutment 26 on the bolt, whereby'the latter may be retracted from extended pos tion upon rotation of the disc. Thus It will be seen that the combination mechanism of the lock is actuated by the stem of the motor meter, the base 8 of which carries the indicating mark 9, which cooperates with the fgraduations marked. 0 to 25 on the top 10 o the cap. By knowledge of the proper combination, the operator may setthe clearance recesses 30 and 31 to free the bolt, which then will be free to be projected by its 3 ring 20. The lock casin is fixedly secure to the cap 10 by. suitable astenings 12.

In the present instance the cap does not screw. directly upon the radiator ni le, as is customary, but fits rotatably'on out side thereof, as shown in Figs. 1 and 3: An

14, which ongages threads' 15 on theinside of the radiator .nipple, is rotatably mounted within the earance recess 31 for the cap and is held therein by a ring 16, fitted tightly within the cap; it may also be secured therein by screws 17, threaded into the cap adjacent said ring and bearing with their heads against the bottom of the latter. A spring-disk washer 19 is inserted between the cap and the bushing, to detain the cap in desired rotary position when the bolt 11 is retracted. The bushing has an aperture 18 to receive the bolt 11.

The operation is as follows:

When the bolt 11 is freed from the re taining ring 21 and flange 25, it may be projected into the seat, as in Fig. 1, to lock the bushing 14 to the casing 7 and, consequently, to the cap. When, therefore, the cap is rotated to the left, the bushing unscrews from the radiator nipple and the cap and its motor meter can be removed. When the bolt 11 is retracted, the operative connections between the cap and the bushing is removed, so that rotation of the cap has no effect upon the bushing to unscrew it and the cap cannot be removed without again setting the combination. This presents a certain safeguard against theft of the motor meter and obviates the necessity of the car owner or driver ca ing a key with him. In the event the re ative position of the cap and bushing is not such as to permit the bolt to move directly into the seat 18, the bolt will automatically find such position upon rotation of the cap relative to the bushing, so that further rotation will be efliective to unscrew the latter from the nipple.

A feature of the invention is the complete housing of the bushing within the ca as, in this particular embodiment, by the epending circumferential part of the cap, whereby it is rendered impossible for a person not acquainted with the combination to manipulate the bushing or lock mechanism from without.

Various modifications in the details of assemblage of the parts may be made without departure from the spirit of the invention; wherefore the detailed description and the drawing of a particular embodiment are to be taken in an illustrative and not in an unnecessarily limiting sense.

Moreover, while I have illustrated and described the invention as applied to the locking of a radiator capin position, it will be evident that the same is a plicable in many relations to the locking 0 a cap upon a nipple or stud to prevent unauthorized tampering therewith. I
